Is resumed and the operation of the second conveyor 3 is started, and when the lower beam 162 on the front side moves on the second conveyor 3 as shown in FIG. 23 (a), the elevating body as shown in FIG. 27, and when the rear end of the loaded product W approaches the front end of the first conveyor 2 as shown in FIG. 4C, the lifting body 37 of the second lifter 22 is raised, and )
The upper surface of the support claw 32 of the elevating body 37 is brought into contact with the lower surface of the rear end of the upper beam 161 at the center of the skid S as shown in FIG.

The elevator 37 is driven forward in the direction of arrow X in synchronism with the forward movement of the loaded articles W by the two conveyors.
As shown in FIG. 4 (a), when the lower beam 162 on the rear side of the load W whose rear end portion of the upper beam 161 is supported by the support claws 32 of the elevating body 37 reaches the position above the interval n, the first The forward drive of the conveyor 2, the second conveyor 3, and the lifting / lowering body 37 is stopped, and the square abutment U is supplied to the banding position of the article R by the square abutment transfer loader 90 in the same manner as described above. After supplying the contact plate T to the article R and the banding position on the corner contact U by the loader 122 in the same manner as described above, the banding machine 10 performs banding.

After the banding, the forward drive of the second conveyor 3 and the lifting / lowering body 37 is resumed to advance the banded product Z, and as shown in FIG.
After moving on the conveyor 3, the elevating body 37 is lowered as shown in FIG. 3C, and then the elevating body 37 is driven forward to stop at the forward end position, as shown in FIG. As described above, the first lifter 21 and the second lifter 22 return to the reference position, and the banding of one load W is completed.

The banded product Z obtained is the second conveyor 3
And then transferred to a front conveyor (not shown) on the front side, or transferred from the second conveyor 3 onto a carrying-out conveyor different from the second conveyor by a transfer device (not shown) or the like. Is provided to the subsequent process.

As described above, the load W is loaded on the first conveyor 2
In the gap n between the second conveyor 3 and the lower end of the upper beam front end of the skid S, the first lifter 21 (specifically, the elevating body 2
7), and the lower surface of the rear end of the upper beam is supported by the second lifter 22 (specifically, the elevating body 37).
The lower beam 162 does not fall into the gap n and the transfer onto the second conveyor 3 becomes difficult, and the loaded product W is
It is smoothly transferred from the conveyor 2 to the second conveyor 3. During the transfer, the banding machine 10 automatically performs banding on the load W on which the skid S portion is supported by the first lifter 21 or the second lifter 22, so that the load W is not banded. For this reason, it is not necessary to move to a different place by a crane or the like, and banding can be automatically and efficiently performed without requiring any manpower during transportation by the conveyor.

The L-shaped bending of the square plate t in the pressing device 65 of the square contact feeding devices 60a and 60b is as follows.
In parallel with the above banding, that is, FIGS.
May be carried out between the time when the corner press is removed from the press device 65 by the corner press transfer loader 90 during the entire banding process shown in FIG. And supply of the square plate into the press device 65 by the square plate transport loader 80;
The bending of the square plate in the press device 65 and the supply of the obtained square abutment U to the banding position by the square abutment transfer loader 90 are performed by the banding machine 10 on the front lower beam 1.
By performing between the banding at the position 62 and the banding at the position of the lower beam 162 on the rear side, it is possible to supply the angular contact U without delay to the banding performed while conveying the load W on the conveyor. In addition, it is possible to efficiently perform the banding of the loaded product while manufacturing the corner abutment U.

The present invention is not limited to the above embodiment. For example, the first lifter 21 and the second lifter 22 may be supported not on the common base 20 but on separate bases so as to be able to move back and forth. The lifting bodies 27 and 37 are connected to the carriages 25 and 35 by the parallel links 26 and 36 as described above.
Instead of moving up and down while rotating via, it may be moved up and down linearly in the vertical direction.

Further, in the above specific example, the corner contact feeding device 60
Since the a and 60b are provided on both sides of the first conveyor 2, the entire apparatus is compact and does not take up much space.
By integrally connecting with the frame of the conveyor 2, even if the width of the loaded article W (article R) is changed, complicated control such as changing of the square coin transport path in the square coin supplying device is required. The advantage is that, by only adjusting the conveyor interval P, a band can be supplied to the upper corner portion of the article R and the banding can be performed without any trouble. In the case of a fixed or fixed-amount feeding device in which the square-amount transfer path is variable, the square-amount supply device may be provided at another position, and the first conveyor 2 may have a constant conveyor interval. Is also good.

Further, as the square contact feeding device, a device other than the above-mentioned specific example, such as a device having a stocker for storing a separately prepared square contact without the press device 65, can be used. When the money U is not used or when the worker supplies the money U manually, the money supply device may be omitted. Further, other types of conveyors such as belt conveyors may be used as the first and second conveyors, and a device for adjusting the conveyor interval P of the first conveyor 2 is an electric drive having a right-hand screw and a left-hand screw. A device having another configuration such as a synchronous drive device using two screw rods of the formula may be used.

In the above specific example, the plate supplying device 120
Is configured to be able to accommodate a plurality of lengths of the holding plate T, and is moved back and forth by the air cylinder 127. Therefore, even when there are a plurality of widths of the loaded article W (article R). It has the advantage that the structure can be simplified because the plate loader 122 only needs to be movable in one direction, but it has a structure that moves two-dimensionally on a plane. Is used, the moving table 124 may be of a fixed type, and if the width of the load W is constant, it is sufficient that the movable table 124 can accommodate one type of square plate t. Further, when the contact plate T is not used, or when the worker supplies the contact plate T manually, the contact plate supply device may be omitted.

FIG. 25 shows an example of a banded product Z which is banded by a banding device in which the square contact feeding device is omitted as described above, and FIG. 26 omits the plate feeding device as described above. FIG. 27 shows an example of a banded product Z which is banded by the above-described banding device, and FIG. 27 further shows an example of the banded product Z in a case where both the square contact metal supplying device and the plate supplying device are omitted. In the figure, the same parts as those in FIG. 17 are denoted by the same reference numerals. In addition, these banded products Z
In the above-described specific example,
And / or by programming the plate supply device 120 not to operate.

Further, according to the present invention, various articles other than the above-described article R obtained by paper-wrapping a laminated product of steel sheets are mounted on a skid having various configurations other than the above-described skid S, such as one having a lower beam fixed to the lower side of the plate-like body. The present invention can also be applied to a device for banding a loaded product. In addition, banding of a loaded product can be performed on a portion other than the above specific example, such as a central portion in the front-rear direction of the loaded product.
